United Airlines has installed Starlink on over 50% of its fleet (53.4%), including most of its regional two-cabin aircraft, which likely operate on routes like OKC->TUS. However, there are zero direct observations of Starlink on this specific route, and recent news confirms Starlink primarily on mainline and regional routes but not specifically on OKC->TUS. Given the lack of route-specific sightings and zero observed flights with Starlink, the probability is anchored near the empirical observation rate (0.0) but adjusted upward moderately due to fleet coverage and rollout status, capped conservatively at 0.40 to reflect medium confidence in partial route coverage.
